Here are new and updated NSNs that PS captured in 2022. While this is a complete list of what we reported over the past calendar year, it’s probably not a complete list of all new, updated or rescinded NSNs. Why’s that?
That’s because PS must be aware of new or updated NSNs. Sometimes we get notified by a command like TACOM, CECOM, DEVCOM, etc. Sometimes we’re informed of an NSN change by an equipment specialist or LAR and asked to publish the change.
More often, it’s our readers that notice an incorrect NSN in a TM or try to order a part and discover that the NSN they’re using is no longer valid and they reach out to PS. After some investigation on our part, we find the correct NSN and inform the reader. Normally, an article is published to inform the field of the new or updated NSN. This means we need your continual support.
